Phaetus aeWorthy™ ASA-GF Filament 1kg Spool

Phaetus aeWorthy ASA-GF — glass-fiber reinforced ASA, 1.75mm, 1kg

ASA reinforced with 10% chopped glass fiber. You get ASA's real strengths — UV stability and weather resistance for parts that live outdoors — plus the stiffness, dimensional stability and low-warp behavior the glass fiber adds. Phaetus also tunes this for lower odor than standard ASA, which is welcome on long prints. The finish is a matte, slightly textured "carbon-fiber-look" surface that hides layer lines.

What it prints well: functional outdoor parts, automotive trim and brackets, enclosures, jigs, and larger models where plain ASA would warp. It is not a cosmetic high-gloss material — it is an engineering filament that trades shine for stiffness and stability.

Print settings (Phaetus)

• Nozzle: 250-270°C
• Bed: 100-110°C
• Enclosure: required. ASA cracks and delaminates in a draft, and it releases styrene VOCs — run it in an enclosure in a ventilated room.
• Diameter: 1.75mm

Hardware you need

This filament is abrasive — a hardened nozzle is required. Glass fiber will wear out a standard brass nozzle in a few spools and your dimensional accuracy goes with it. Run a hardened steel, DLC-coated, tungsten carbide, or ruby nozzle. If you do not already have one, add a hardened nozzle to your order before you load this — it is not optional with GF filament.

Drying

ASA absorbs moisture over time. If the spool has been open, or you see stringing, steam, or popping at the nozzle, dry it (roughly 70-80°C for 4-6 hours in a filament dryer) before printing. Store it sealed with desiccant between uses.

Note: one reseller lists the glass-fiber content as 15-20%; Phaetus's own spec states 10%. We list it as Phaetus states it.
